- Use pacman -Syu instead of -Sy to prevent partial upgrades (Arch footgun) - Run manual AUR build in subshell to avoid leaving cwd in temp dir - Use append_if_missing for flatpak.conf instead of overwriting - Show warning on test Flatpak install failure instead of silent suppression Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# COSMIC Store Installer for Omarchy (Arch Linux + Hyprland)
|
|
#
|
|
# This script installs System76's COSMIC Store on Omarchy so you can browse
|
|
# and install Flatpak applications through a graphical app store — similar
|
|
# to GNOME Software or KDE Discover, but built with the COSMIC desktop toolkit.
|
|
#
|
|
# Why this script exists:
|
|
# Omarchy uses Hyprland (a Wayland compositor), not COSMIC Desktop or GNOME.
|
|
# The COSMIC Store doesn't natively know how to launch apps through Hyprland's
|
|
# portal system. This script bridges that gap by:
|
|
# 1. Installing the COSMIC Store from AUR
|
|
# 2. Setting up Flatpak with the Flathub repository
|
|
# 3. Creating a wrapper that tells COSMIC Store to use Hyprland's portal
|
|
# 4. Configuring environment variables so Flatpak apps appear in the
|
|
# Omarchy app launcher (Walker/Elephant)
|
|
# 5. Symlinking Flatpak .desktop files so they're discoverable
|
|
#
|
|
# The result: you get a full graphical app store that works seamlessly with
|
|
# Hyprland, and installed Flatpak apps show up in your app launcher.
|

# Install dependencies:

# base-devel: Build tools needed to compile AUR packages
|
|
# git: Cloning AUR repos
|
|
# flatpak: The Flatpak package manager itself — sandboxed app
|
|
# distribution system used by COSMIC Store
|
|
# xdg-desktop-portal: D-Bus interface that lets sandboxed apps talk to the
|
|
# desktop (file pickers, notifications, screen sharing)
|
|
# xdg-desktop-portal-gtk: GTK fallback portal for dialogs
|
|
# xdg-desktop-portal-hyprland: Hyprland-specific portal (screen sharing, window picking)
|
|
# desktop-file-utils: Provides update-desktop-database for app menu integration
|
|
#
|
|
# We use -Syu (full system upgrade) rather than just -Sy because syncing
|
|
# the package database without upgrading can cause partial upgrades on Arch,
|
|
# where newly installed packages link against library versions that aren't
|
|
# installed yet. This is a well-known Arch footgun.

✅ Done.

|
Next:
|
|
1) Log out of Hyprland and back in (applies environment.d so Omarchy launcher sees Flatpaks).
|
|
2) Open "COSMIC Store" from your apps menu (it uses Hyprland portal via wrapper).
|
|
3) Verify Flatpak apps appear in the launcher. Test:
|
|
flatpak run org.gnome.Calculator
|
|
|
|
If COSMIC can't "Open" an app, you can also launch the store directly with:
|
|
env XDG_CURRENT_DESKTOP=Hyprland cosmic-store
|
|
|
|
To remove everything later:
|
|
yay -Rns cosmic-store-git # or: sudo pacman -Rns cosmic-store-git
|
|
rm -f ~/.local/share/applications/com.system76.CosmicStore.desktop
|
|
sudo rm -f /usr/local/bin/cosmic-store-hypr
|
|
rm -f ~/.config/environment.d/flatpak.conf
|
|
# (then log out/in)
|
|
